“…This comparison shows excellent agreements with the measurements for all resonant modes. Table 2 presents the comparison between our calculated frequencies and those measured and calculated in [20,24] for high order modes of circular microstrip antenna with a dielectric cover. Numerical results obtained coincide well with the published results in the literature and with measured data.…”

In the present paper, a rigorous full-wave analysis for determining the resonant frequency and half-power bandwidth of covered circular microstrip patch antenna is presented. Green's functions of the structure are determined in Hankel transform domain. Galerkin's is used in the resolution of the electric field integral equation. The TM set modes issued from the cavity model theory are used to expand to unknown current on the patch. For an isotropic substrate, it is demonstrated that the bandwidth decreases with increasing ratio of superstrate-substrate thickness for high permittivity and low thickness of superstrate. Also, we show that the resonant frequency and bandwidth are highly dependent on the permittivity variations along the optical axis. The validity of the results is tested by comparing results with those published in the literature. Also, numerical results for the variation of the resonant frequency and half-power bandwidth of the substrate-superstrate configuration for high order modes, and for several values of substrates thickness are presented.

Progress In Electromagnetics Research, EMW Publishing, 2010, vol. 18, pp 169-183. Progress In Electromagnetics Research C, Vol. 18, 169-183, 2011 IMPROVING Abstract-The moment method technique has been improved to investigate the scattering properties of high T c superconducting circular antennas with anisotropic substrate in multi-layered configuration. In this method, the electric field integral equation for a current element on a grounded dielectric slab of infinite extent was developed by basis functions involving Chebyshev polynomials. An improved analytical model is presented taking into account anisotropic substrate, superconducting material for the circular patch and multilayered structure. To validate the theoretical results, an experimental study has been performed for a perfectly conducting circular patch on a single layer, with and without air gap. Good agreements were obtained between our theory and measurements. Effects of temperature and thickness of a superconducting film are also reported and discussed. The performances of high T c superconducting circular antennas were improved by the use of uniaxial anisotropy substrate and multilayer configuration.
